Hi I get this error when I try and deploy the emulator but it only happens when I run the database on the emulator it works fine before I do this. I run the database just to see if the database gets populated. Does anyone know how to solve this problem.

Make sure to stop your application (or QA tool which would be opened if you "run" the database) before redeploying the database.|||How do I do that? Do I just shut down the emulator?
|||If you are using the Query Analyzer on the emulator, select the Tools menu, and select Exit. If you are using your app to view the data, shut down the app by providing exit functionality. Or go to Start, Settings, System tab, Memory, Running Programs tab, and Stop any program accessing the database from there.
